Kinematic viscosity for water on Mars

In summary, the relationship between atmospheric pressure, viscosity, and density for liquid water is primarily dependent on temperature. There are online resources available to estimate the range of dynamic viscosity and density values for varying atmospheric pressures and temperatures on any planet. However, the viscosity of water may also be qualitatively observed by its behavior in different temperatures, such as being more "gooey" in the winter compared to summer. This information can be found in resources like ASME steam tables or online.

Hi - I am trying to understand the relationship between atmosphere pressure, viscosity, and density - specifically water. Is there are way to estimate a range of dynamic viscosity and density values based on varying atmospheric pressures and/or temperature that I could use on any planet. Thanks for any help.

Are you talking about liquid water or water vapor?

Hi, thanks for responding. I am talking about liquid water.

The density and viscosity are essentially functions only of temperature (which you can look up online).

You can qualitatively observe water's viscosity dependence on temperature by paying attention to the behavior of water and windshield wipers on your automobile. Technically speaking, it's a lot more 'gooey' in winter than in summer. That caused me to look up viscosity versus temperature of water , found it in ASME steam tables before the days of internet. (Really i was trying to figure out why in wintertime in S Florida Biscayne Bay is so much choppier than in summer.. But that's another thread..).

1. What is kinematic viscosity for water on Mars?

Kinematic viscosity is a measure of how resistant a liquid is to flow. It is the ratio of a liquid's dynamic viscosity (a measure of its internal friction) to its density. In the case of water on Mars, it refers to the ability of water to flow on the Martian surface.

2. How does kinematic viscosity for water on Mars compare to Earth?

The kinematic viscosity of water on Mars is significantly lower than that on Earth. This is due to the lower atmospheric pressure and gravity on Mars, which affects the density of water and results in a lower resistance to flow.

3. What factors affect the kinematic viscosity of water on Mars?

The kinematic viscosity of water on Mars is primarily affected by the atmospheric pressure and temperature. Higher temperatures decrease the viscosity, while lower temperatures increase it. Additionally, the composition and purity of the water can also impact its kinematic viscosity.

4. How is kinematic viscosity measured for water on Mars?

Kinematic viscosity can be measured using various instruments, such as a viscometer, which measures the flow of a liquid under specific conditions. For water on Mars, scientists may also use remote sensing techniques to estimate kinematic viscosity based on surface features and atmospheric conditions.

5. Why is kinematic viscosity for water on Mars important to study?

Understanding the kinematic viscosity of water on Mars can provide insights into the planet's past and present geology and climate. It can also help with planning future missions and potential human exploration of Mars. Additionally, studying the kinematic viscosity of water on Mars can help us better understand the potential for life on the planet.
